A method is presented for indicating the dispensing of a predetermined amount of a material in a dispenser (10) having a dispensing portion (30) which dispenses the material during periods of operation at a frequency or intensity which can be varied. The inventive method includes determining the amount of time the dispensing portion is operational; calculating a dispensing score representative of the time of operation of the dispensing portion multiplied by a factor representative of the frequency or intensity of dispensing; and producing a signal indicating the dispensing of the predetermined amount of the material to be dispensed when the dispensing score is at least equal to a predetermined total score required for dispensing a predetermined amount of material. A dispenser incorporating such a method is also described.
